Metal powder process to manufacture stable nanowires

Japanese researchers have developed a method for heating nanocarbon tubes and metal powders to produce nanowires in a vacuum. The nanowires produced by this method are stable and have low chemical activity compared to nanowires produced by other methods. This method is best suited for metals that can be converted to gases at relatively low temperatures, such as ruthenium, osmium, iridium and ruthenium. From this way, the metal atoms are almost completely filled with the cavities of the carbon nanotubes. The study found that the metal ruthenium has an inner diameter of about O. A 76 nm carbon nanotube can obtain a wire composed of a single atomic chain. This first true one-dimensional nanowire is chemically stable after exposure to air for a month. Â
